Before the rise of the Aztec Empire, the Valley of Mexico was dominated by the city of Azcapotzalco, which had Tenochtitlan as its vassal. Eventually the latter grew too big for its britches, and so it allied with Texcoco and Tlacopan in a successful campaign to overthrow their overlord, which was suffering from political instability after the death of its longtime ruler Tezozomoc (who apparently lived until the age of 106?).
So what if Azcapotzalco defeats the soon-to-become Triple Alliance, and reaffirms its dominance over the Valley of Mexico? Could its rulers use the failed rebellion as an excuse to end the defeated cities' political autonomy, and thus potentially centralize to a degree similar to what the Purépecha/Tarascans achieved, rather than the mostly independent tributaries and vassals the Mexica had?
